Unable to create a sentry_organization_repository resource for a GitLab integration

[sdzhong]

According to the resource documentation, creating a sentry_organization_repository resource for a GitLab integration should be supported, but the provider returns an Unable to create, got error: POST https://sentry.io/api/0/organizations/XXX/repos/: 400 map[error_type:validation errors:map[__all__:Error Communicating with GitLab (HTTP 404): 404 Not Found]] as follows:

Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the following symbols:
  + create

Terraform will perform the following actions:

  # sentry_organization_repository.XXX will be created
  + resource "sentry_organization_repository" "XXX" {
      + id               = (known after apply)
      + identifier       = "XXX"
      + integration_id   = "NNN"
      + integration_type = "gitlab"
      + organization     = "XXX"
    }

Plan: 1 to add, 0 to change, 0 to destroy.

Do you want to perform these actions?
  Terraform will perform the actions described above.
  Only 'yes' will be accepted to approve.

  Enter a value: yes

Manually adding the repo to an existing GitLab integration works from the Sentry UI without an issue.

Deleting the added repo and re-running Terraform as aforementioned results in the same error; this issue is reproducible and does not seem related to Gitlab token.

Just solving same issue. identifier is not slug but internal gitlab Project ID (Settings > General > Naming, description, topics)

  + resource "sentry_organization_repository" "gitlab" {
      + id               = (known after apply)
      + identifier       = "1"                 # Project ID
      + integration_id   = "NNN"
      + integration_type = "gitlab"
      + organization     = "XXX"
    }
